It’s relatively easy to propagate your anthurium plants by taking cuttings, but it’s also a little boring, because the new plants will be exact copies of their parent plants. If you would like to produce new varieties of anthurium flowers, you will have to grow them from seed. The hardest part about growing them from seed is getting seeds to form in the first place. To do this, you need to learn how to pollinate an anthurium.
Anthurium flowers are perfect, meaning that they contain both male and female parts, but they usually do not self pollinate, because pollen is not produced until after the stigma stops being receptive to pollination. This ensures that wild plants are cross pollinated as much as possible in order to increase the genetic diversity of the species. So unless you have two plants and are willing to cross pollinate them, you will have to store pollen until your plant is ready for pollination.
To pollinate your plant, the first thing you have to do is collect pollen. Wait until pollen is produced and use a fine paint brush to collect pollen and put it into a small vial. If you are self pollinating a plant, store this vial in the freezer until the next flower is ready for pollination. Or you can use the pollen immediately if you are cross pollinating.
Next, you need to pollinate at the right time. After a flower blooms, watch for the stigmas that are found on the spadix to secrete nectar. When this occurs, they are ready for pollination. Using your paint brush, dust pollen liberally over the stigmas. Once you have done this task, the next step is to wait. If your efforts are successful, the spadix will begin to swell as it produces berries, which contain the seeds.
You may have to wait up to a year before the seeds are ready. You will know that the seeds are ready when the berries fall off the spadix. At this point, you can pop the berries and extract the seeds from the inside of the berries. You should plant these seeds immediately or they will die. After a few weeks, the seeds will begin to sprout and you will be well on your way to producing new varieties of anthuriums.
